> I would not even be quick to assume this is some sort of unknown betrayal to his family

But (unless "unknown" is doing a lot of work in your sentence) Huang literally said this in his letter to NVidia employees: "I was unfaithful to my wife. My actions hurt her and our children. There is no excuse for what I did. I am deeply sorry."

Otherwise, I agree with a lot of what you said. In the 2000-2015 timeframe, I really idolized a lot of these successful tech leaders - they seemed incredibly smart, hard-working, and talented (though also of course lucky). But over time I came to the realization that many of them just fundamentally think very differently than I do, and I view that other way of thinking with disgust. The main issue is it seems like nearly all of their relationships are transactional, and they have a lack of empathy and willingness to be ruthless that is simply anathema to me.
